Product Application

Pool operators need to be confident that the disinfectant is correctly dosed and controlled, for both the health and comfort of the bathers. Disinfection of swimming pools is usually achieved using chlorine. Adequate free chorine is required to prevent infections, while eye irritation is minimised by keeping the combined chlorine residual as low as possible.
Studies from many countries including the United States, the United Kingdom, and Europe agree that pool water is safe when the chlorine content is maintained at 1.5 mg/L (or higher) and the pH is between 7.0-7.4. Although experts generally believe that the risk of infection from swimming pools is small, because when the virus enters the water, it will be diluted, and active disinfection will make the virus inactive. However, only regular effective testing and management of swimming pool facilities can fully ensure the water safety of swimming pool users.
